Description
Affiliated technical field
The utility model relates to a kind of screw extruder discharging building mortion that is applicable to expanded feed.
Background technology
The discharging building mortion of the expanded feed screw extruder of using has single template now; Being extruded pressure and temperature and the final products expanded level that material goes out before the machine can be controlled by the template of changing different perforated areas; Template can be changed, but unadjustable.
Summary of the invention
In order to overcome existing expanded feed screw extruder building mortion single template is only arranged, to being extruded the defective that pressure, temperature and uniformity before material goes out machine do not possess regulatory function, the utility model provides a kind of discharging building mortion that middle pressing mold is set in the middle of template and screw shaft, guarantee extruded material pressure, temperature is adjustable, pressure distribution is even.
The technical scheme that its technical problem that solves the utility model adopts is: constitute the discharging building mortion by template, outlet rectification cone, template hold-down nut, middle pressing mold, round nut, extrusion chamber, guiding cone, restrictor ring and adjusting washer (disk) etc.; Pressing mold in the middle of being provided with in the middle of template and the extruding screw axis, this centre pressing mold is cylindrical, two plane breach making external screw thread and match with spanner, there is circular hole the centre, and the two sides all has the water conservancy diversion taper hole; The template hold-down nut is fixed on template by being threaded the discharge end of middle pressing mold, and middle pressing mold screws in the extruding and discharging cavity by being threaded, and screw-in depth is adjustable, adopts round nut locking; The guiding cone of threaded connecting rod is assembled in the extruding screw end, the rectification cone that assembling is screwed in the middle of the template, improve the uniformity that pressing materials distributes, the both sides of pressing mold water conservancy diversion taper hole in the middle of cone in the middle of the cone of extruding screw end and the template is configured in respectively, screw in the degree of depth of extruding and discharging cavity or the thickness of the spacer of regulating sleeve on the extruding screw axle by pressing mold in the middle of regulating, can regulate the gap of guiding cone and middle pressing mold taper hole, realize the adjusting of discharge openings area.
The beneficial effects of the utility model are: owing to adopted the discharging building mortion of pressing mold in the middle of the configuration, the discharge openings area can be regulated, pressing mold separates the restraining force of material generation and the shaping function of template in the middle of making, help keeping the extrusion chamber degree of filling, increase the input of mechanical energy, guarantee that extrusion pressure is evenly distributed, under the prerequisite that does not change the template nib, change the temperature and pressure of logistics in the extruding and discharging chamber, help improving the productivity ratio and the product quality of screw extruder.

In the drawings, 1. template 2. exports rectification cone, 3. soket head cap screw, 4. template hold-down nut, 5. middle pressing mold, 6. round nut, 7. extruding and discharging cavity, 8. guiding cone 9. is fixed cover, 10. restrictor ring, 11. adjust packing rings, 12. cored screws, 13. screw shafts.
The specific embodiment
A kind of screw extruder discharging building mortion, as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, Figure 11, Figure 12, shown in Figure 13.Three circular holes are arranged in the middle of the template (1), and outlet rectification cone (2) has three screwed holes, and it is fixing with template (1) to export rectification cone (2) with three soket head cap screws (3).To assemble the template (1) of outlet rectification cone (2) and pack in the template hold-down nut (4), the discharge end of pressing mold (5) in the middle of template hold-down nut (4) is fixed on template (1) by being threaded.Middle pressing mold (5) external cylindrical surface is made fine thread, and intermediate cylindrical is made and can it can be screwed in extruding and discharging cavity (7) with spanner for the two parallel breach of bottom surface of wrench operated, and screw-in depth is adjustable, adopts round nut (6) with its locking.Middle pressing mold (5) two ends all have the water conservancy diversion taper hole, and the center is a straight hole, and the taper hole relative with guiding cone (8) is identical with the tapering of guiding cone (8).The screw portion of guiding cone (8) passes and is fixed cover (9), be connected with screw shaft (13) end screw, the cylindrical bottom portion of guiding cone is made can be for two parallel planes of wrench operated, the screw rod of guiding cone can be screwed in the screw of screw shaft (13) end with spanner, and restrictor ring (10) spacer (11) and cored screw part axials such as (12) are compressed by the annular end face that is fixed cover (9), when the round nut of back-outing (6), available spanner screws out certain-length with middle pressing mold (5) from extruding and discharging cavity (7), clearance opening area in the middle of this moment between the cone of taper hole and the guiding cone (8) of pressing mold (5) increases, will make extruding and discharging cavity (7) centre be extruded material temperature and pressure will reduce; Otherwise as middle pressing mold (5) being screwed in extruding and discharging cavity (7) certain-length, above-mentioned clearance opening area reduces, and being extruded the temperature and pressure that material goes out before the machine will improve.By quantity that increases or reduce adjusting washer (disk) (11) or the adjusting washer (disk) of changing different-thickness, can regulate the relative position of guiding cone (8) and middle pressing mold (5), when adjusting washer (disk) (11) gross thickness increases, the taper hole of middle pressing mold (5) and the clearance opening area between guiding cone (8) cone reduce, otherwise then increase.
